Abstract: Over the last 6 years INO (National Optics Institute of Canada) in collaboration with the MTQ (Ministère des Transports du Québec) have been developing and testing a new technology called the LCMS (Laser Crack Measurement System). The LCMS is composed of two high performance laser profilers that have been set up in such a way as to be able to measure complete transverse profiles of a road lane. In addition to acquiring high resolution 3D road profiles, algorithms were developed to analyze the 3D data in order to automatically extract crack data including crack type (transverse, longitudinal, alligator and sealed cracks), crack severity and crack location (presence in bands). Further testing of the system was done in order to demonstrate that the system can also evaluate rut depth, detect pot holes and patching as well as measure the macrotexture of the road surfaces.
